Image pickup apparatus, lens apparatus, imaging system, control method, and storage medium

Abstract

An image pickup apparatus is attachable to and detachable from a lens apparatus configured to provide tilt drive by an actuator. The image pickup apparatus includes an image processing unit configured to add a reverse tilt imaging effect to an image acquired through the lens apparatus using image processing, and a processor configured to determine whether to add the effect to the image using at least the image processing or at least the tilt drive.

What is claimed is: 
     
         1 . An image pickup apparatus connected to a lens apparatus configured to provide tilt drive by an actuator, the image pickup apparatus comprising:
 an image processing unit configured to add a reverse tilt imaging effect to an image acquired through the lens apparatus using image processing; and   a processor configured to determine whether to add the effect to the image using at least the image processing or at least the tilt drive.   
     
     
         2 . The image pickup apparatus according to  claim 1 , wherein the processor is configured to determine whether to add the effect to the image using only the image processing, only the tilt drive, or both the image processing and the tilt drive. 
     
     
         3 . The image pickup apparatus according to  claim 2 , wherein in a case where the processor determines that the effect is to be added using only the image processing, the processor is configured to add the effect through the image processing of the image processing unit while fixing an optical element of the lens apparatus,
 wherein in a case where the processor determines that the effect is to be added using only the tilt drive, the processor is configured to perform the tilt drive without performing the image processing, and   wherein in a case where the processor determines that the effect is to be added using both the image processing and the tilt drive, the processor is configured to add the effect through one of the image processing and the tilt drive, and then add the effect through the other of the image processing and the tilt drive.   
     
     
         4 . The image pickup apparatus according to  claim 2 , wherein in a case where the processor determines that the effect is to be added using both the image processing and the tilt drive, the processor is configured to add the effect through the image processing and then add the effect through the tilt drive. 
     
     
         5 . The image pickup apparatus according to  claim 1 , wherein before the effect is added, the processor is configured to move a tilt position of the lens apparatus to a position where a lens principal plane of the lens apparatus is parallel to an imaging surface. 
     
     
         6 . The image pickup apparatus according to  claim 1 , further comprising an operation unit operable by a user,
 wherein the processor is configured to determine a method of adding the effect according to a signal obtained from the operation unit.   
     
     
         7 . A lens apparatus attachable to and detachable from an image pickup apparatus having an image processing unit configured to add a reverse tilt imaging effect using image processing, the lens apparatus comprising:
 an optical element;   an actuator configured to move the optical element to perform tilt drive; and   a processor configured to control the actuator,   wherein the image pickup apparatus determines whether to add the effect to the image using at least the image processing or at least the tilt drive, and   wherein the processor is configured to control the actuator to perform the tilt drive in a case where the processor receives a signal from the image pickup apparatus instructing to perform the tilt drive to add the effect.   
     
     
         8 . An imaging system comprising:
 a lens apparatus configured to tilt drive by an actuator; and   the image pickup apparatus according to  claim 1 .   
     
     
         9 . A control method for an image pickup apparatus connected to a lens apparatus configured to provide tilt drive by an actuator, the control method comprising:
 a determining step of determining whether to add a reverse tilt imaging effect using at least image processing to an image acquired through the lens apparatus, or to add the effect using at least the tilt drive; and   an adding step of adding the effect using a method determined by the determining step.   
     
     
         10 . A control method for a lens apparatus attachable to and detachable from an image pickup apparatus that includes an image processing unit configured to add a reverse tilt imaging effect using image processing, the control method comprising the steps of:
 receiving a signal from the image pickup apparatus instructing to move an optical element to perform tilt drive in order to add the effect; and   controlling an actuator to perform the tilt drive according to the signal,   wherein the signal is received in accordance with a determination of the image pickup apparatus as to whether to add the effect using at least the image processing to an image acquired by the image pickup apparatus through the lens apparatus, or to add the effect using at least the tilt drive.   
     
     
         11 . A non-transitory computer-readable storage medium storing a program that causes a computer to execute the control method according to  claim 9 . 
     
     
         12 . A non-transitory computer-readable storage medium storing a program that causes a computer to execute the control method according to  claim 10 .
